Device for electromagnetically securing the door leaf of a multi-leaf revolving door against unwanted movement, e.g. due to wind pressure, out of the operating position radial to the cylinder segment-shaped limiting walls of the revolving door comprises assigning to each door leaf (1) a rotation-independent safety catch locked by a magnetic brake (MB) as a controllable securing device whose driving part (holding bolt (7)) is fixed to the door leaf frame (6) and whose driven part (forked arm (9)) is fixed to the door frame (roof construction (31)) so that it rotates. |
